To all it-may'concem:

Be it"known'fithat' I,""EUcnNE C. BERN- HEIM','- a citizen'of'fthe'United States, and resident ofSout-hbri e, in the county ofWorcester and State 0 Massachusetts, have invented certain new anduseful Improvements' in Finger-Piece Eyeglasses, of which the followingisa specification.

My invention relates to eye-glasses of the kindin whichpivoted,"spring-pressed nose clamps arev provided together withfingerpieces for operating these. clamps.

The object of my invention is to provide a structure of this characterwhich will en- "able adjustments to be made readily :-=and which willhave the springs located advantageously so as not to weaken the structure at thepivotsoi the nose-guards. 4

In the accompanying drawings I have illustrated various constructionsembodying my present invention, Figure 1" being a front elevation of oneform of my Invention with parts in section; F g. 2 1s a plan'v1eWthereof; Fig; 3 is a vertical section substantially on line3-3of l 5Fig. 4 is a detail view ofthe spring shown in the construction of Figs..2 and 3; Fig. 5 is a perspective view of'the so-called post'used in"this construction Fig. 6 shows anothler form of spring adapted for usein connection with this construction; Fig. 7 afront elevation of anotherform of-my invention;

' Fig. 8 illustrates in perspective the combined post and spring used inthis form of my invention; Figs. 9, 10, 14 and 15 illustrate inperspective other forms of combined clips and springs; Figs. 11 and 13illustrate two forms of my invention, in which the post is made in onewith the bridge and F gs. 12 and 16 are similar views of a constructionin which bridge, post and spring are made integral.

A indicates the lenses which are held by V means of cars B and screws O,or in any other approved manner. The-ears B are connected rigidly orformed integral with boxes C which, in the form illustrated by Figs. 1,2, 3 and .7 are in the nature of sleeves open both atthe top and at thebottom. Into these sleeves are fitted the ends of the bridge D, thevert-ical' members E of the posts and the stationaryends of the springsF, which ends are of-an inverted U- shape, as shown in Figs; 3 and 4.These Patented Sept. 6, 1910-.-

E in the vertical pos't portion E is prefer I ably elongated verticallyso that when the scr'ewG has been loosened the post may be:

readily adjusted up or down. The horizontal. member 'E of the post isprovided with an apertureE to receive "the vertical pivotj H- ofjalever, the forward end of which, 1, forms a finger-piece, while the rearend, J, constitutes the nose clamp. The movable end F ofthe springengages a suitable bearing .K of the lever and has a tendency to pressthe clamp J against the nose.

As illustrated in Fig. 6 the spring FF may be provided with anintermediate coil F In each case I prefer to'have the end F of thespring in loose engagement with the bearing portion K so that-when saidbearing portion is adjusted vertically together with the post E--E aproper en-- gagement of the spring will be" preserved since the'bearingportion will simply slide along the spring. However, it is not necessarythat the spziug should have a sliding engagement witlt the bearingportion during I adjustment since the U-shaped configuration of theattachedspring end allows itto be readily adjusted up or down within thebox C so that, 'if desired, the lever and the spring may be adjustedvertically to the 7 same extent.

The construction shown in Figs. 7 and 8 differs from the onefirst-described by a somewhat diiierent shape of the bridge D and by thefact that the ends of the bridge ex-' tend upward into the box C insteadof downward, and second, by making the post E E of one piece with thespring F which, in this particular construction, ex-

tends from the lower end of the vertical post member E. v

Instead of making the spring of one piece with the post, it may be madeseparate, yet connected rigidly with the post; thus Fig. 9

shows one end of the spring Fflscrewthreaded to fit into a correspondingaperture at the forward edge of the vertical post member E. Fig. 10shows a further way of combining the spring with the post; in this casethe spring F extends first down- 1 ward from the horizontal member ofthe post at its forward portion and then upward, rearward and inward.

In Figs. 1a and 15 I have shown a construction in which the spring F ismade integral with the vertical member of the post and extends rearwardfrom the lower edge thereof, is then formed with a coil whose axis ishorizontal or approximately so and finally has its free end directedupward.

In Figs. 13 and 16 I have shown a plate L (perforated at L) madeintegral with, or rigidly secured to the bridge 1), D*.

In Fig. 11 a complete post is shown having a horizontal and a verticalmember the latter. connected with the bridge D; in

Figs. 13 and 16 the bridge is connected only with a vertical member orplate L and in these two constructions a separate post oat the characterherein described will have to be provided for carrying the pivot of thenose clamps. In Fig.16 the vertical member L integral with the bridge Dis also integral with the spring F which is arranged in substantiallythe same manner as in Fig. 8.

Fig. 12 shows that I may combine in one structure the bridge D the postE, E and the spring F the construction being practically the same as inFig. 10 except that the bridge D is connected directly with the lowerend of the vertical post member.

I claim as my invention:

1..The combination of the lens, the box connected therewith, the postcarried by the box and adjustable vertically, the nose clamp pivoted tothe post, and the spring having one end held at the box and the otherend in loose engagement with a bearing portion of the clamp, so that theclamp, during its vertical adjustment, will slide along the spring.

2. The combination of the lens, the box connected therewith, the postcarried by the box, the nose clamp pivoted to the post, and

the vertically adjustable spring, independent of the pivot, having oneend stationary and the other in engagement with the nose clamp.

3. The combination of the lenses, the boxes connected therewith, thebridge connecting the two boxes, independently adjustable posts carriedby said boxes, nose clamps pivoted to said posts, and verticallyadjust-able springs engaging said nose clamps.

at. The combination of the lenses, the boxesconnected therewith, thebridge connecting the two boxes, independent vertically adjustable postscarried by said boxes, nose clamps pivoted to said posts, and springsattached to the boxes and having a sliding engagement with the noseclamps as the latter are adjusted.

5. The eombination'of the lens, the box connected therewith and formedas a sleeve the bridge having one end within saidsleeve, the post havinga vertical member within the sleeve and a horizontal member exteriorlythereof, the nose clamp pivoted to the horizontal post member, and thespring having one end secured within the sleeve and the other inengagement with the nose clamp.

6. The combination of the lens, the box connected therewith, the bridgejoined to the box, the pivoted nose clamp supported above the box andvertically adjustable rela tively thereto, and the nose clamp actuatingspring supported above the box and vertically adjustable relativelythereto independently of the nose clamp.

In testimony whereof I have signed this specification in the presence oftwo subscrib ing witnesses. 4
